PERM UTATlON-PADLOCK.

SPECIFICATION forming part of Letters Patent No. 557,155, dated March31, 1896.

Application filed October 6, 1894. Serial No. 525,157. (No model.)

To @ZZ whom t may concern:

Beit known that I, THOMAS D. ScEUGGs, a citizen of the United States,residing at Florence, in the county of Lauderdale, State of Alabama,have invented a new and useful Improvement in Combination-Locks,of whichthe following is aA full, clear, and exact description.

This invention relates to an improved padlock; and it consists of theconstruction, arrangement, and combination of parts, all as hereinafterdescribed and claimed.

The object of the invention is to provide a simple and reliablecombination-padlock having changes of combination. This I accomplish bymeans of a new combination of a lever-hasp, in connection with disks ortumblers having radial slots, one of which tumblers is made with aspindle integral with it, solely for the purpose of securing a means ofchanging combination on the outside.

Reference is to be had to the drawings accompanying and forming a partof this speciiication, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure l is a view of case with hasp A in locked position and showingtumbler D in alinement 011 center-post b. Fig. 2 is the lock-case, withcenter-post b', having in its upper part the socket b for the shorterspindle f" of tumbler F, Fig. 6. Fig. 3 is the front plate or cover ofthe lock-case. Fig. 4 is one of the tumblers, having a radial slot d andgroove or slot d. Fig. 6 is the other tumbler, (the lock in this casehaving but two,) having a radial slot f"" and a lug or pin f, alsohaving a spindle with a square part f', which spindle may be madeintegral with the tumbler or otherwise immovably secured to it, as shownin this figure. In Fig. 7 G is a washer used to separate the twotumblers D F. The screw I, with a washer J, secures the dial-knob E,Fig. 5, to the square part f of the spindle or tumbler F. Fig. 8 is thelever-hasp, having a wedge-shaped lift a.

The case B has a center-post b of the'length of the combined thicknessesof the tumbler D and the washer G. Upon this center-post the tumbler Dand washer G revolve, as in Fig. l. The center-post b has a socket b forthe reception of the part f of spindle of tumbler F, and the part f3 ofspindle of tumbler F is inserted through opening c of front plate O, sothat the round part f of the spindle may turn in opening c', the lug f"engaging with slot d of tumbler D. The dial-knob E, with its squareaperture e, made to embrace square part f of spindle of F, is securedthereon by means of a washer J and screw I.

The top O is secured to the case by means of pins .9 s s s, which areriveted after being inserted through holes tt t t of the top C.

The alinement of the radial slots dfm of the tumblers D and F with thewedge-shaped part a of the lever-hasp A is effected by turning thedial-knob E to the right, when the lug or pin f" of the tumbler Fthereby engages the end of the groove or slot d/ of tumbler D, by whichmeans the tumbler D may be revolved far enough to effect the alinementof the radial slot CZ of tumbler D with the radial slot 'W' of thetumbler F. By turning to the left the slot d of tumbler D is left inalinement with the wedge-shaped lift a of the hasp A, said slot d beingso situated upon the periphery as to come into line with the wedgeshapedlift a before lug f reaches the other extremity of slot d. of the othertumbler D.

The two radial slots d f being in alinement with the wedge-shaped lift aof leverhasp A, the hasp may be elevated for opening the lock ordepressed for locking it, the tumblers D and F being revolved by thewedge-shaped lift a entering the alined slots (l fm. When hasp A isclosed, as in Fig. 1, any turn to right or left of the tumblers D or Fwill throw slots d and fm out of alinement, when the wedge-shaped lift aof the hasp will be kept locked by the peripheries of tumblers.

To change the combination, the screw I of the spindle of tumbler F istaken out and the knob-dial E turned relatively one-fourth, onehalf, orthree-fourths around and replaced upon spindle and again made fast bythe screw I in the hole f".

Where for any reason the change of combination may be undesirable, thescrew I may have the slot by which it is turned led off after beingsecurely inserted, and the dialknob E be thus fixed immovably to thespindle of tumbler F.

Having thus fully described my invention, what I desire to secure byLetters Patent is- The combination with the rear case-plate IOO providedwith a receptacle for the tuinblers,` VWedge-shaped lift a; theCover-plate ortop for and a center-posh having a socket for the holdin-gthe parts in place and the dial-plate Io shorter spindle portion of thetumbler F, the or indicator-plate, substantially as Specified. longerpart of said spindle portion being reetangular in cross-section at f,the tumbler F THOMAS D. SCRUGGS. having the radial slot fm and the pinf", d Vitnesses:

the tumbler D having radial slot CZ and inp J. A; MCKINSEY,

termal curved slot d', the hasp having the J. T. VORLEY.
